广角数码儿童视网膜成像系统引导下激光光凝治疗早产儿视网膜病 变

目的 观察在广角数码儿童视网膜成像系统（RetCam II）在激光 光凝治疗早产儿视网膜病变（ROP）中的应用价值。 方法 回顾分析连续 发现的阈值ROP或阈值前Ⅰ型ROP患儿共30例58只眼， 其中36只眼为阈值前Ⅰ型ROP，19只眼为阈值ROP，3只眼为外院冷冻术后有冷冻遗漏 区ROP；1区ROP 8只眼，2区ROP 50只眼。54只眼 （93.1％）进行了一次激光光凝， 4只眼（6.9％）进行了2次激光光凝。 应用半导体532 nm激光经双目间接检眼镜激光光凝周边视网膜无血管区。手术前后 分别进行RetCam II眼底检查，手术中对激光光凝遗漏区即刻进行补充治疗。治疗后随访时 间3～11个月，平均5-5个月。 结果 54只眼1次激光光凝术后1～3周反 应良好，ROP病变得到控制。4只眼行第2次激光光凝术后，2只眼病变静止、消退；2只眼发 生后极 部局限性牵拉性视网膜脱离。随访结束时2只眼（3.4％）发生视网膜不良结构后果。 结论 激光光凝手术前后行RetCamⅡ检查在治疗ROP时能够有效避免激光光凝 “遗漏区”，提高一次激光光凝成功 率，减少手术后视网膜不良结构后果发生率。

Wide-field digital pediatric retinal imaging system-assisted photocoagulation for retinopathy of prematurity

Objective To observe the therapeutic efficacy of wide fi eld digita l pediatric retinal imaging system (RetCam II) assisted photocoagulation on ret in opathy of preamturity (ROP). Methods The clinical data of 30 p atie nts (58 eyes) with threshold ROP or prethreshold type I ROP were retrospectively analyzed. The non perfusion area underwent semiconducting photocoagulation wit h 532 nm under indirect binocular ophthalmoscope. In 30 patients, prethreshold ty pe 1 ROP was found in 36 and threshold ROP was in 19; missed area after cryotherapy in other hospital was observed in 3; Zone 1 ROP was in 8 and z one 2 ROP was in 50. Fifty four eyes (93.1％) underwent one time photocoagulat i on and 4 eyes (6.9%) underwent a second. Ocular fundus was examined by RetCam II before and after operation. The missed area after cryoth erapy was at once supplemented during surgery. The follow up duration was 3－ 11 m onths (average of 5.5 months). Results Fifty four eyes which had under gone one time photocoagulation had good result 1－3 weeks after surgery and the disease was controlled. In 4 eyes which had undergone t he second photoco agulation, the disease alleviated after the operation in 2 and local posterior t ractional retinal detachment occurred in 2. At the end of follow up duration, u n favorable retinal structural outcome was observed in 2 eyes (3.4%). Con clusion R etCam II assisted photocoagulation can avoid missed area during the operation， enhance successful rates of first photocoagulation and reduce unfavorabl e retinal structural outcome rates.
